Qualitative relationships between a black hole (BH) interpreted as a spin system and BH superradiance are considered for Kerr BHs. A proposed connection between the appearance of superradiance and the existence of a nonvanishing spin entropy is supported by the result of Starobinski (1973) regarding wave amplification in BHs. Energy emission from a rotating BH is viewed in a framework wherein a BH considered as a thermodynamical object with a given temperature (on the event horizon) accounts for Hawking's emission, while a BH considered as a spin system with given negative temperature (on the inner horizon) accounts for superradiance and the nonthermal spontaneous emission. Also discussed are analogies between BH emission and laser emission.
